Barnacles and headcrabs
Half Life 2 Aftermatch is due for release on PC on the 28th April 2006. According to PC Gamer magazine, "[Aftermath] deals with the events and issues set in motion during Half-Life 2. You've done critical damage to the Citadel. The whole place is going to go up, taking out City 17 and what's in its immediate radius. You and Alyx are leading the flight from the city getting up close and personal with some of the creatures and sights from the end of the game."
With the success of Half Life2, HL2 Aftermath should be a huge success in 2006.
